Background technology
Although the construction technology of shield tunnel reaches its maturity both at home and abroad, shield quantity rises year by year, and the geological conditions of application is more extensive, and in subway work, the soil body is excavated by shield machine, carries out disturbance, destroys its initial balance, thus causes earth's surface to deform.But have many factors to affect earth's surface deformation, such as: the buried depth in tunnel, section, construction method, support form and hydrogeologic condition in shield-tunneling construction.In order to further appreciate that Ground Settlement Monitoring, and make shield-tunneling construction that surrounding environment influence to be minimized, tunnel is used shield construction to cause surface subsidence to make substantial amounts of research work by Chinese scholars, obtain some Forecasting Methodologies, mainly had: empirical method, model testing method, analytic method and numerical analysis method etc..
Empirical method is the shape according to the tunnel subsidence groove after excavating, and collects the data of monitoring, by the form of curve to represent, by ground settlement result, determines characteristic parameter, thus predict the sedimentation value on earth's surface.Analytic method is built upon on theoretical basis, thus obtains earth's surface deformation, and the various soil bodys are had the strongest adaptability.Simple boundary condition and initial condition are easily analyzed by analytic method, so stratum is assumed to uniformly by analytic method, plane strain problems, this makes it apply by bigger restriction, more cannot consider the execution conditions impact on strata deformation.In research shield tunnel construction causes the change of formation displacement, numerical simulation analysis method is a kind of important method of prediction earth's surface deformation.Mainly include limit elements method, finite difference calculus and boundary element method etc..Model testing method is in fixing laboratory, for the concrete condition of engineering, sets up model, is simulated test, thus draws the research method of ground movement rule.
Once there is sedimentation phenomenon in landform; extremely serious consequence can be brought to the people of surrounding; light then affect trip; heavy then can crisis life; such as the sedimentation accident of No. four lines of Shanghai Underground, Hangzhou Subway Xiang Hu station Beijing University area cave-in accident etc., research and develop the monitoring system of stratum deformation in a kind of shield-tunneling construction extremely urgent.
Stratum deformation immediate cause is caused by shield driving, mainly has the reduction of excavation face unstability, level of ground water, thrust correction excessive, frequent, hole body soil instability, shield body to leak with the frictional force of hole body, lining cutting generation gap, grouting pressure, lining deformation, lining cutting behind.Although the immediate cause of stratum deformation has a lot, but substantially can be divided into following 4 classes: the elastic-plastic deformation that the release of (1) reservoir stress produces, cause stratum counter-force to reduce;(2) soil pressure increases the compression produced, and causes vertical soil pressure to increase or stratum counter-force reduces;(3) elastic-plastic deformation that additional soil pressure produces, causes acting on soil pressure and increases;(4) elastic-plastic deformation produced with the physical property change of soil and time deformation, cause stratum bearing capacity to reduce.
